PIHIL RV Condenser Fan Blade 10-1/2" D-Shaped 1/2" Bore — Fits Dometic Brisk & Duo-Therm, OEM-Compatible

The PIHIL 3313107.015 is a direct-fit 10-1/2" condenser fan blade designed to restore airflow and reduce noise in Dometic Brisk RV air conditioners and Duo-Therm heat pumps.

When an RV rooftop unit starts running loud, vibrating, or fails to move enough air, the problem is often a worn or damaged condenser fan blade. This OEM-compatible PIHIL fan blade replaces several old part numbers and fits a wide range of Dometic Brisk Air and Duo-Therm Brisk models. Built to the same key dimensions as the original, it has a 10-1/2" diameter, 3" thickness, and a D-shaped 1/2" shaft bore for a secure motor fit.

How will replacing this blade affect my RV's cooling performance?

Installing a properly sized blade restores the designed airflow through the condenser, allowing the system to reject heat efficiently and maintain set temperatures with less strain on the compressor. A balanced, undamaged blade also reduces vibration that can loosen other rooftop components.

• Restores original condenser airflow for stable cooling.
• Reduces motor load and improves energy efficiency.
• Minimizes vibration and prolongs rooftop unit life.
